Stop stop stop and stop using the device immediately! Once you use it again, it may cause the file overwritten situation which means your original files may be overwritten by the new files. To get back the recovery image, you can boot your disgo 8000 first. Then use this software to get the files back, here is the website: http://www.uflysoft.com

Search google to do a hard reset, I had the problem and after doing a hard reset it helped me and my tablet is working fine now. I don't really remember which keys it was but there are three keys to keep pressed and after that it will reset your tablet and if everything is ok it should work perfectly after that.
It would be nice if the manufacturer would also put that in the manual, because when I received my tablet I had to calibrate the screen and that didn't really help me. Also the tablet was working really slow and took a lot of time for everything, plus the fact that the keyboard kept pressing all sorts of other keys then that I wanted to press.
I hope this will help you and that your tablet will work fine for you.
Let me know if you had any success.

Hi there,

We are sorry to hear that the device is freezing and not working as expected.

Please try the following which may help to resolve the issue.

1) Ensure that the Video/Image files you are trying to view are compatible with the tablet. Compatible files are located on the packaging and in the User Manual. You can also locate this information on the website, mydisgo.com

2) If you have not already done so, we would advise that you update the device to version 2.3. The update procedure can be found at the following page; tinyurl.com/8000update

3) If the Gallery app only freezes when accessing files on the SD card (and not internal memory), please try using the alternative memory card slot or test using a different memory card.

I do hope this helps to resolve the issue.

If you require any further assistance, please do not hesitate to contact us at mydisgo.com/support

Thanks, mydisgo.com
